Since mpg on highway is OK, the problem is either your driving habits (heavy acceleration after each stop?) or severe driving conditions (lots of uphill/downhill?).

You would think that since you go downhill about as much as you go uphill, the mileage would average out same as level ground, but Mother Nature just doesn't work like that (never a free lunch!).

If your idle is too fast during stopped car, it might suggest an intake air leak somewhere. This might lead to poorer city driving than highway driving, but that's a guess. Inspect all vacuum lines and connections carefully.

good luck
